BUCKLE.

Application mea January 21, l1911. serial No. 603,844.

To all whom tt may concern:

Be it known that I, HENRY W. FALsTRoM, a citizen of the United States of America,

residing at Newark, Essex county, State of v New Jersey, have invented certain new and useful Improvements in Buckles, of which the following is a full, clear, and eXact description.

This invention relates to an improvement in buckles, the object being to provide a simple but effective device of this character that is capable of firmly holding a beltstrap, for instance, around the body.

One of the principal objects of this invention is to doaway with prongs or the like for gripping or penetrating a strap.

Further features of my improvement will hereinafter appear.

I will now proceed to describe my invention in detail, the novel features of which will be pointed out in the claim, reference being had to the accompanying drawing, forming part hereof, wherein:

Figure 1 is a central longitudinal sectional view, on an enlarged scale, of my improved buckle, a portion of a strapbeing also illustrated; Fig. 2 is a cross-sectional view taken on a line a-a in Fig. 1; Fig. 3 is a similar V view the section being taken on a line b-b in Fig. 1, the strap being omitted; and Fig. 4 is an enlarged fragmentary longitudinal sectional view of my improved buckle showing the position of the tongue before the jamming thereof.

Referring to the drawing my improved buckle consists of a jaw member 1, comprising a bottom plate 2 and a top plate 3 connected by a wall 4. Adjacent one end of the jaw member 1, I provide an inclined plane or wedge 5 (preferably stamped out of the bottom-plate) which acts as one element or means for firmly holding the strap member 6, the strap member 7 being secured to the bottom plate 2 of the jaw member, as at 8 and 9, the portion 8 being a socket to receive the end of the strap member 7 and the element 9 one of a plurality of fingers which pass through the said strap member 7 and are turned over as shown.

To coperate with the inclined plane or wedge 5, to hold the strap member 6, I provide a loosely mounted longitudinally slidable tongue 10 consisting of a base member or plate 11 having an upwardly extending end flange 12 conveXed as at 13 (see Fig. 2). To retain the slidable tongue or plate 10 in position upon the bottom plate 2 of the j aWf member 1 and limit the rearward movement thereof, I provide guides, 14 which are stuck vup from the material of the said bottom plate 2 as shown, there being enough space 15 (Fig. 4) between the upper surface of the bottom plate 2 and under surface of the horizontally disposed members of the said guides to permit of the upward riding of the tongue 10 upon the inclined plane or wedge 5 when the strap member 6 is pulled in the direction of the arrow 16 in Fig. 1. As can be seen in the various views of the drawing, the inclined plane 5 is integral with the material of the bottom plate 2. To prevent the strap member 6 from being prematurely withdrawn from the jaw member 1, I provide the upper plate 3 with a depending iange 17.

When desiring to use the buckle it is moved sidewise on to the strap member 6, the said strap member passing through the open end 18 of the jaw member 1, while the tongue 10 is positioned as shown in Fig. 4, the iange 12, of the said tongue, being high enough to contact with the under surface of the said strap member when said tongue is positioned as shown. The flange 12 is conveXed as at 13 for the purpose of allowing the strap to pass thereover and slightly in 'contact therewith. After the buckle has been positioned, as above described, the strap member 6 may be gripped by pulling the same in the direction of the arrow 16, at which time the tongue 10 will slide forwardly and up the inclined plane 5 until further movement thereof is arrested by the wedging of the strap 6 against the under surface of the top plate 3. Fig. 1 illustrates the tongue 10 in its jammed position. To remove the strap member 6, it is pulled in the direction of the dotted arrow 19 (Fig. 1), at which time the tongue 10 will slide off the inclined plane 5 to its released position. The buckle may then be removed from the strap by being moved sidewise.

Having now described my invention, what I claim and desire to secure by Letters Patent is:

A buckle comprising a bottom plate, a portion of said bottom plate, at one end thereof, being stamped to form an inclined plane, guides carried by said bottom plate, said guides being located in alinement with the inclined plane, and being stamped out of the metal of the bottom plate, a longitudnally slidable plate having its rear end and a Wall connecting one edge of the top located under said guides, the forward end and bottom plates, all arranged so as to proof the slidable plate being upturned to form vide an open-sided buckle, substantially as a flange, the rearward movement of said shown and described.
